UNITED STATES PATENT OLIVE HEALY, OF PATERSOX, NEW JERSEY, ASSIGNOR OF ONE-HALF TO JOHN INGLIS, OF SAME PLACE.

LIGHTING SEWlNG-MACHENES.

SPECIFICATION forming part of Letters Patent No. 294,128, dated February 26, 1884. Application filed March 30, 1883. (X model.)

[0 all whom it may concern.-

Be it known that I, OLIVE HEALY,a subject of the Queen of Great Britain, residing atPaterson, Passaic county, State of New Jersey, have invented a new and useful Improvement in Lighting Sewing-Machines, of which the following is a specification, reference being had to the ac eompanying drawings, forming a part thereof.

The object of my invention is to automatically light sewingmaehines by electricity.

The invention consists in a holding device of new construction, and in securing the same to the stationary arm of the machine, and in the construction and adjustable arrangement of a hollow tube in said holding device, and in suitably securing an incandescent lamp provided with a shade to the end of said tube, and in connecting said lamp with a dynamo or producer, uovelly secured to the sewingmachine by a knuckle-j oint, by insulated wires, and in connecting said dynamo machine or producer with the driving mechanism of said sewingmachine, which will be hereinafter more fully explained. I Figure l of the drawings is arear elevation of an ordinary sewing-machine having my im-,

provements thereon. Fig. 2 is an end elevation of the same. Fig. 3 is a section of the stationary arm, &c. Fig. 4 is a front section of standards, &c.; and Fig. 5 is a modification of some of the parts shown in Fig. 1.

a represents a sewing-machine of ordinary construction,havin g a stationary arm, K, to the end of which arm I secure, by means of a clip, E, a holder, F. The clip is constructed in parts, and is provided with a projecting flange, to which flange is secured, by a suitable bolt, a holder having a corresponding flange, as shown in Fig. 3. The flanges and holder are recessed in front, to accommodate a hollow tube, N, of yoke shape, which I adjustably secure in the'recess of the holder F by thumbscrew G. The outer end of the tube N, I provide with an incandescent lamp, A, having a 5 shade, M, which I suitably secure to the end of the tube. I connect the lamp A with the dynamo or producer B by means of insulated conducting-wires D and D. The wires are taken from the lamp A through the tube N along the arm K, and down the same to and through suitable openings formed in the top or table it therefor, to the dynamo or producer B, which I secure to the frame a, and suitably secure the wires D D to the studs 75 of the dynamo B. The dynamo is secured to the ma chine a by a clip, V, and knuckle Y, forming thereby a knucklejoint. The dynamo-shaft H is provided with a friction-wheel, O, having an elastic ring, Z, arranged in a circumferential groove formed therefor in the periph- 6o cry of the same, which is arranged to be in frictional contact with a balance-wheel, b, that is arranged on a stud, d, secured to the frame a. A driving-wheel, 0, attached to the wheel b is also arranged on the stud d, as shown in 65 Fig. 1.

Suitably secured to a stud in the drivingwheel 0 is a crank-arm, c. The opposite end of said arm is secured to the treadle f, arranged on shaft 9. The driving-shaft of the sewing-machine is connected with the drivingwheel 0 by a band, 8, which connects with a like wheel secured to the wheel j.

In practice the treadle f is put in motion by the foot in the ordinary way, which, by means of the crank-arm c, imparts motion to the balance-wheel b and drivingwheel 0 located on the shaft II. The accumulated motion imparted to the dynamo or producer B by the shaft H creates or evolves a current of electricity, which current so produced by the producer B is conducted by the wires D and D to the lamp A, where an incandescentlight of one or more candle-power is produced by the producer in its contact with the driving mechanism of the sewing-machine (1, which light so produced is concentrated on the needle p and work on the table it by the lamp A and shade M without obstruction or shadow, owing to the location of the lamp A in the holder F above the needle, work, &c.

lVhen the devices are used in the modified form, and the dynamo or producer secured to the top or table h, and the wheel 0 on the shaft H of the dynamo B brought into contact with the wheel j, and the sewing-machine operated by power, the light-producin g means is greatly increased thereby. The motion transmitted from the driving-wheel c to the wheel j by the band 8 gives motion to the arm 0 and needle 1) by means of the needle mechanism in the ordinary way.

IOU

2 wares- The machine a is provided with the ordinary oil-safe,o-, flap 72v, drawer 'i, needle-bar p, tension m lever a, tension 0, and winder w, all of which are used in the usual way.

By my invention sewing-machines are automatically lighted when in use, and the light continuous, as the driving mechanism is kept in constant motion when threading the me dle, arranging the work, &c., by throwing off the band sin the usual way, which action. stops the needle mechanism while the work under manipulation is being arranged on the table h and needle threaded, both of which actions are greatly facilitated by means of ample and unobstructed light from the lamp A.

My invention is adapted for all sewing-machines, and may be applied thereto, and by its use thereon machines in dark rooms and places where insufficient light exists have the producing means of light at hand.

I do not herein broadly claim either the dynamo or the lamp, they being old.

Vhat I do claim, and desire to secure by Letters Patent, in a sewing-machine, is-

The combination of the holder'and stationary arm, the holder provided with recess to accommodate the tube, and thumb screw for holding the tube adjustably therein, the holder secured'to the stationary arm by a clip, and clip for securing said holder to the arm, and hollow tube for holding the lamp, and lamp suitably secured to said tube, the lamp having a shade, and insulated wires suitably secured to said lamp, the wires passing through said tube and connected with the dynamo, and dynamo, the dynamo arranged in frictional contact with the driving mechanism of said machine, and frame to which the dynamo is secured by a knuckle-j oint, and driving mechanism for operating saiddynamo and needle, substantially as set forth.
